Application filed .Tune 25, 1925.

41'- havc invented new and useful improvements in printing presses. which appertain generally and are particularly adapted for use in printing indicia on matter to be mailedA in lieu of the paper stamp now used and as described in the present specifications and-illustrated in. the accompanying drawing's l f..v 1= l Heretofore numerous .attempts have been made-t design arinachiiie of this character which wouldv comply with the requirements of'thelaws governing the use of such a press and especially with respect to prevent its surreptitious or fraudulent use; the .principal-obiect of my invention is to'provide a relatively s1mple compact, and durable machine, embodying the requisite functional' characteristics laforesaid, in which impressions that have not been paid vfor cannot be made, and in which false records or readings of meters cannot be hidden, or which cannot be fraudulently adjusted or tampered with evenby custodians of the keys to the press, without leaving evidence thereof.

"From, a functional or mechanical viewpoint.'aiiotlier object of my invention is to provide in'such a' press a yieldable platen.

that will provide an automatic make ready and thus produce a distinct impression on matter of varying thickness and uneven surface. y

Another 'object of iiiy .invention is to pro be reversed when started until the completeV cycle of movement in either direction is completed.

A further object of my invention is to provide a means to supply ink to the'type of said press in such a way that great numbers of impressions may be made Without manual effort or attention, and for this purpose I have supplied a ribbon carrying ink and mounted on spools, which spools are rotated automatically by the printing arm seriai No. 39,558.

To guardmember 28 is held type protecting shield 571 by means of:pin'58, this protecting shield- 57 f is most-clearly shownl 1n normal -position in Fig. 3` and in printing positionin.Fig..9. When in normal position` this'protecting` shield. 57 covers the face of the typev 60 and makes itimpossible for an impression Sor' indicia .to be; made either by the use of themechani'sm, or by tampering,or by an upward pressure, of any matter against the face of the type until thel said protecting shield has been automatically removed from the face of the type in the course of thc regular printing operation.

Printing member 32 has passingr through it date type holder 59, to the lon-'er -end ot which is attached interchangeable type 59"; this holder '59 is contained. within a tube'59, permanently attached totheprintnurr member 32 and covered with a screw cap 59C, making it accessible to change the date of the type at any time.v Permanently attached to the lower face of the printing mcmbcr 32 is type 60, with which to print, thc major portion of which type lcan only be removed .from the. printingmember-by; partly dismantling :the press, it beingnecessary to remove shaft 26 :andlraise printing,r

`rives access to the"said type 60.- EWhen Y printingmember 32, together with the type 60. is in inormal pofsitionin the: pleS'S, it is?A complet'ely enclosed-on 4all four sides-bythe guard vmember 28 and. isfcovered on its-lowerl mg member 32, thus making it impossible to j grain access to the type without partially.

dismantling tht` press. but permits free use' of-type .60Min full normal operation {of-.the f press. i. Attached to guard member-farms 25 are .the

various members operating and controlling l the type inking ribbon 61, which .consistof parts as follows:` Bearing arms 62, which carry stops 62A and are attached to guard member arms 25 and ,which carry theribbon spools 63, and through ribbon spools 63 and the arms 62 pass lshafts .64,.which arejperlUU manently fastenedto said spools 63, andto the right end ofshafts 64 are fastened ratchet wheels 65` and tothe left end -of shaft 64 are fastened braketension wheels 66which are held undertension by the spring brake167;l ratchet wheels 65 are operated by ratchet pawls 68. which are snspendinjgffrom rocking` arms' 69 by pins 7() andhcld under tensionbyspl'ings 7l. and rocking arms 69 a re connected togethcr and held under tension by spring 72; the action of pawls 68 and-rockingA arms 69 are both controlled by the automatic ribbon actuatingr block 73, which rides on guide shaft 74; block 73 is operated by bar 75, which is connected by links 76 to guide shaft74A and said bar'75 is held under tension by sp1-ing 77., and the guide shaft'74 passes through bearings 78, which are fastened to right hand guard box arm 25. Fig. 3 shows the above described parts ofthe ribbon control in a normal or non-printing: position with block 73 rcsting r against rear pawl 68, which in this position is engaged with rear ratchet wheel 65 to wind ribbon upon `rear spool 63. Fig. 9` shows the same parts of the ribbon control'n'ith the mechanism in printing position and shows block 73at `the forward point of its movement when winding the ribbon upon the rear spool, as above described, .showing rear rocking arm 69 in the forward position resting against stop G2^, thus placing rear pawl 68 in the forward engaged position against rear ratchet 65. the tension for these two ribbon spools 63 is the brake 67, illustrated in Fig. 6; Fig. 10 shows the block 73 in a position to wind the ribbon y upon the forward'spool 63 and is standing in the normal or non-printing position with forward rocking-arm 69 and forward pawl 68 in normal position, and shows by broken lines the position of pawl 68 when it is moved forward at the full stroke of the mechanism during the printinor operation, at which point-it has moved the tf orward ratchet wheel and; forward spool 63 part of a revolution, sufficient-to wind a-portion of the ribbon 61 thereon. This Fig. 10 further shows the relative positions of links 76 when the block 73 is in the winding position above described, and in `broken lines shows the links-76 in thevposit-ion occupied when the block 73 is operating rear ribbon spool 63. It will thus bc seen that the lnearis for actuating the vsaid pawl mechanism to'successive advance and automatic reverse of the ribbon is accomplished by the members as set forth in the foregoing part of this para.- graph, and that the action which takes place is as follows: When' theribbon moving in either direction has unwound its full length from one spool to't-he other, or is subjected to an abnormal tension, one of pawls 68, which is in' contact' with actuating block 73, willvprevent the movement of the said block 73,"which will subject, through arm 75, a pressure -upon links 76, thus reversing their position relative 4to guide bar 74 and forcing guide bar 74 to cause block 73 to exert pressure against the opposite pawl, thus reversing'the direction in which the ribbon spools are travelling. Guide shaft 74 is operated through curved pin 79 and arm 80. and shaft 81 and connecting links 82. which are connected to the rear cndvof and operated by printingr arm 31. Fig. 4 shows the rear end of guide shaft 74, its rear bearing 78, and its connection to links 76, and the spring 77 connected to base plate 20, which holds them under tension and which, when the ribbon control mechanism is reversed, is passed over center and holds links 76 under the same tension in the opposite position.V

The position shown in Fig. 4 of these parts represents the machine in normal position and the ribbon control operating to wind on thc rear spool, as shown in Fig. 3. Fig. 4 further shows the connection of guide shaft 74 pin 79, which loosely couples arm 80; Fig. 2 shows the connection of arm v80 with shaft 81, as also does Fig. 1. Links 82 connecting shaft 81 to printing arm 31 are shown in Figs. 1, 2 and 4, the forward and backward movements-of guide shaft 74 .are14 controlled and operated entirelyby, printingarm 31 through the above describcdconnections, thus completing the" mechanical action of the ribbon'control and the reverse thereof.y 7o Nos. 83 to 113 inclusive show the/varioust parts of the automatic-looking mechanism' by which the press is locked against surrep-- titious or unlawful.fuse 'and the .-rel'easirigf mechanism of thesaid locking"mechani'smg 75 83 being the masterlock working onath'e;V left of printing arm 31 and vSli-'being an .auxiliary lock operating on :theVri'ghtPosaid' arm 31; the locks-83 andf84'ae pivotediby* pin 85 to block 86 attached? to:basefplatsi-201;fao' and-are held #under -tension by; spi-'ing 87, i which is attachedj to post =88g=whioh"'is'fast'=1' ened to base plate 20;jft-hisspring 87,-'by'i means of a connectingpin `89;\acts 'asfltenfi sion spring topull lock 83 l'andfauxiliaryflock 85 84 into' lockedposition'againsti pi-*n 84@ 'which passes f through and proectsl A--erut =-on -either 1 sidecf printing arm 31,2assho7wn in'F-igi'11.' v Attached to and part-offlock'=83-'fis trivpa'rmf 90, which is yconfined#-andi:releasedl by tripriNff-r 91, and this trip 91 moves on movalleia-rmf 92, which arm 92 is fasteneditliroughfvtiie frame of'the downward-'count meter dby; pin 94, and movable?"arm` 92 5isf heldrzldown: by spring 95,^and said movablearmig has "U51 a stop 96 'which A reatsvom thedmmward count meter- Ibed plate 97', .fthe iddwnwardf: count meter 93 isoperatedfby:ar-1598,` coni: nected to -andacutated b'yipri'n'ting arm 311,5; which, lthrough connecting roda-99,' rocks-'100v shaft 100,'which passesthrou `fthedowna:l ward count meter andffrotates 'index wheelsE 1 101, which wheels have -vc'rossislts 102.13 I'Dhe: said cross slots 102-,:f'.and all zothen. partsmentioned in the foregongpart offthispan-waagraph,'are best'sho'wn inFigssrl, 297,18' and 11.
